Robot cat should fucking get one. And a flamethrower attachment. And some sort of an all-terrain setup that can both "jump" slightly and handle things like stairs.
All he wanted was the simple dignity of a kitty-wheelchair, dammit. IT'S TIME TO MAKE THE HUMANS PAY.
And why the hell didn't they just give the kitty a standard wheel-frame setup like most animals with paralyzed hind legs get? Even if the cat really is the one moving the box, he's still pissed as hell at *being in a box*. At least the animal wheelchair would allow his movements to feel far more natural than just sitting in a box and making it go.
